Detailed Description

Next, the present invention will be described with reference to an embodiment. Fig. 1 shows the shape of the refrigerator 1 according to the present embodiment. However, in fig. 1, the appearance of the main body portion is shown only by a two-dot chain line.

As in the case of the conventional refrigerator, the refrigerator 1 of the present embodiment includes a main body 2 and a lid 3, wherein the main body 2 has an opening 21 that opens upward and is capable of storing and storing the stored items therein; the lid 3 moves relative to the body 2 to open and close the opening 21. As shown in fig. 5a and 5b, a lock device L for holding the lid 3 in the closed state is provided across the body 2 and the lid 3. The refrigerator 1 is rectangular in plan view (see fig. 1). The refrigerator 1 of the present embodiment has an engaged portion, and an engaging portion that engages with the engaged portion.

The lid 3 of the present embodiment is provided so as to be opened on both sides, and in the present embodiment, the lid 3 can be moved relative to the body 2, for example, so as to be moved upward of the opening 21 in a substantially parallel state, and the entire lid 3 can be separated from the body 2. The movement of the lid 3 with respect to the body 2 may be such that one of two parallel long sides in the shape in plan view functions as a hinge by locking one of the operating levers 31 described later, and the lid 3 is lifted up to rotate the lid 3 on the other long side. By this movement, the lid 3 can be brought into the closed state and the open state.

As shown in the perspective view of fig. 4 and the vertical sectional shapes of fig. 5a and 5b, the main body 2 has a fixed shaft (shaft) 22 as an engaged portion. The fixed shaft 22 is fixed to the main body 2. In the body 2 of the present embodiment, the fixed shafts 22 are provided along two long sides of the opening 21 of the body 2. For example, two fixed shafts 22 are provided on each long side of the body 2 at positions symmetrical with respect to the center in the longitudinal direction. As shown in fig. 4, the fixed shaft 22 is disposed outside the opening 21. The fixed shaft 22 of the present embodiment is, for example, a rod having a circular cross-sectional shape.

The cover portion 3 has: a cover body 3A that covers the opening 21; an operation handle 31 as an operation portion for a user to operate from the outside of the refrigerator 1; and a lock member 32 serving as an engagement piece that is interlocked with the operation handle 31 (see fig. 1).

As shown in the vertical sectional shapes of fig. 5a and 5b, the lock member 32 is movable with respect to the fixed shaft 22 of the main body 2. The lock member 32 has a claw portion 321 as an engagement portion engaged with the fixed shaft 22.

The cover 3 has a leaf spring 33 as an elastic portion that is interlocked with the claw portion 321 and has an elastic force.

As shown in fig. 1, the operation handle 31 is provided at the center in the longitudinal direction of both end portions having long sides of the cover portion 3. Further, the operation handle 31 is movable in the vertical direction. Specifically, as shown in fig. 1 to 3, the operation lever 31 is provided in the cover main body 3A so that an inner portion thereof moves in the vertical direction with respect to the cover main body 3A.

When the operation lever 31 is not operated, the operation lever 31 is elastically biased upward with respect to the cover main body 3A by the elastic force of the leaf spring 33. When the operation lever 31 is operated (for example, when the operation lever 31 is pressed down by a user with a force larger than the elastic force of the plate spring 33), the operation lever 31 rotates with respect to the cover main body 3A centering on the rotation axis of the operation lever 31. The operation handle 31 and the lock member 32 are physically coupled by a rod-like member or the like, and are integrally moved (rotated) by the operation of the operation handle 31. Therefore, when the operation handle 31 is moved, the lock member 32 is interlocked. Further, the operation handle 31 and the lock member 32 may be an integral member.

The locking member 32 cooperates with the fixed shaft 22 to hold the lid 3 in the closed state (see fig. 5a and 5 b). That is, the locking device L includes the fixed shaft 22 provided to the body 2 and the locking member 32 provided to the lid 3.

Further, the lock member 32 rotates with respect to the cover main body 3A. The rotation range of the lock member 32 is set to cover a range from the front side of the fixed shaft 22 (see fig. 5a) to a position where the claw 321 is aligned with the fixed shaft 22 (see fig. 5b) with reference to the fixed shaft 22 of the body 2. As shown in the drawing, the lock member 32 extends downward with the lid 3 horizontal with reference to the rotation shaft 322, which is the rotation center of the lock member 32. The lock member 32 of the present embodiment includes a lock main body 323 as an engaging piece main body integrated with the claw portion 321, in addition to the claw portion 321.

The lock member 32 of the present embodiment is formed of a resin such as polyacetal resin or a material obtained by mixing glass into a resin, for example.

The claw portion 321 is movable relative to the fixed shaft 22, and engages with the fixed shaft 22 by an operation from the outside (for example, an operation of the operation lever 31 from the outside), thereby holding the lid portion 3 in the closed state. The claw portion 321 is movable between a locked state (see fig. 5b) in which it is engaged with the fixed shaft 22 and an unlocked state (see fig. 5a) in which the engagement (engagement with the fixed shaft 22) is released. The claw portion 321 of the present embodiment is movable (clockwise in the drawing) so as to approach the fixed shaft 22 from the side close to the opening 21. When the plate spring 33 is operated from the outside with a force greater than the elastic force of the plate spring 33 and a force capable of deforming the plate spring 33 is applied to the plate spring 33, the claw portion 321 moves from the unlocked state to the locked state.

In this way, when the operation lever 31 is not operated from the outside (when the operation lever 31 is in a state of being lifted from the cover main body 3A as shown in fig. 2), the claw portion 321 is always maintained in a state in which the engagement with the fixed shaft 22 is released, and therefore, the cover 3 can be prevented from being held in the closed state without the user's intention. Accordingly, for example, since the cover 3 can be opened and closed by grasping any portion of the cover 3, operability when the refrigerator is used on a narrow fishing boat can be improved. In addition, when the user stores a large number of the fished fish in the refrigerator 1 in order, the user can easily store the fish by opening and closing the lid 3 without operating the lever 31.

The claw portion 321 faces one side of the rotation range with respect to the fixed shaft 22 (see fig. 5a and 5 b). The claw portion 321 of the present embodiment faces the depth side (left side in fig. 5a and 5b) with respect to the fixed shaft 22.

Lock body 323 has a surface 324 facing fixed shaft 22 and a back surface 325 opposite to surface 324. Further, the lock body 323 is provided with a through hole 326 penetrating between the front surface 324 and the back surface 325.

The leaf spring 33 of the present embodiment rotates relative to the cover main body 3A in conjunction with the lock member 32. The plate spring 33 extends downward, for example, on the front side of the fixed shaft 22 with respect to the fixed shaft 22 (the right side in fig. 5a and 5b), and further extends from the front side of the fixed shaft 22 with respect to the fixed shaft 22 to the depth side of the fixed shaft 22 across the fixed shaft 22.

The plate spring 33 includes an abutment portion 331 capable of abutting against the fixed shaft 22. The plate spring 33 of the present embodiment has a shape in which the contact portion 331 is sprung up. The contact portion 331 of the plate spring 33 has a slope that can contact the fixed shaft 22.

The plate spring 33 includes a convex portion 332, and the convex portion 332 continues rearward with respect to the contact portion 331 in a moving direction (clockwise direction in fig. 5a and 5b) in which the plate spring moves from the unlocked state to the locked state. The plate spring 33 includes an extended portion 333, and the extended portion 333 extends rearward continuously with respect to the convex portion 332 in a moving direction from the unlocked state to the locked state.

The moving direction from the unlocked state to the locked state is, for example, a direction in which the convex portion 332 approaches the fixed shaft 22 in the moving direction of the plate spring 33. The front in the moving direction from the unlocked state to the locked state is the front-head side in the moving direction, and the rear in the moving direction from the unlocked state to the locked state is the opposite side to the front-head side in the moving direction.

Further, the plate spring 33 of the present embodiment is attached to the lock main body portion 323. Therefore, the leaf spring 33 and the claw portion 321 are interlocked via the lock main body portion 323, and therefore, a stable operation feeling can be obtained when an operation is performed from the outside (for example, when the operation lever 31 is operated).

The plate spring 33 is inserted into the through hole 326 of the lock main body 323. For example, the plate spring 33 protrudes from the back surface side of the lock main body portion 323 to the front surface side via the through hole 326. Since the leaf spring 33 extends from the back surface side to the front surface side of the lock main body 323 in this way, even when the leaf spring 33 is disposed in a limited space, the length of the leaf spring 33 (for example, the length of the extended portion 333) can be ensured, and therefore, the elastic force of the leaf spring 33 can be ensured. In addition, since the length of the plate spring 33 can be ensured in this way, the degree of freedom in designing the refrigerator case 1 can be improved.

The plate spring 33 is made of an elastic material such as metal or resin. Specifically, the plate spring 33 is made of stainless steel.

When not operated from the outside, the contact portion 331 is maintained in a state of being in contact with the fixed shaft 22, which is a part of the body 2, by the elastic force of the plate spring 33. When the operation is not performed from the outside, specifically, when the operation handle 31 is not operated by the user, the contact portion 331 of the plate spring 33 is in contact with a part of the main body portion 2, and therefore, the claw portion 321 is maintained in a state of being disengaged from the fixed shaft 22 in conjunction with the plate spring 33. Since the contact portion 331 of the present embodiment has a slope, any portion of the slope contacts the fixed shaft 22 having a circular cross section. Accordingly, the contact portion 331 can be reliably brought into contact with the fixed shaft 22.

The convex portion 332 protrudes toward the fixed shaft 22 from the rotational shaft 322 side of the lock member 32, for example. The convex portion 332 constitutes a corner, for example, but the convex portion 332 may constitute a curved convex portion in addition to the corner. In the unlocked state (see fig. 5a), the angle θ formed by the contact portion 331 with respect to an imaginary line connecting the center of the rotating shaft 322 and the center of the fixed shaft 22 is preferably 100 ° to 140 °, and more preferably 120 °. When the angle θ is within the above range, when the contact portion 331 of the plate spring 33 contacts the fixed shaft 22 in a state where no force is applied to the lock member 32 from the outside, a force is generated to rotate the lock member 32 in the unlocking direction about the rotation shaft 322, and thus the unlocked state can be maintained. When the lid 3 is shifted to the locked state, the lock member 32 needs to be rotated in the locking direction with a force exceeding the elastic force of the plate spring 33 around the rotation shaft 322 as a center.

The extension portion 333 is, for example, a rectangular plate bent in an L shape. The length of the first extended portion 3331 of the extended portion 333 extending downward is longer than the length of the second extended portion 3332 of the extended portion 333, for example, the second extended portion 3332 extending from the lower end of the first extended portion 3331 to the depth side of the fixed shaft 22. Specifically, the length of the second extended portion 3332 is 5mm to 20mm, preferably 10mm to 15 mm. By setting the length of the second extended portion 3332 within such a range, the plate spring 33 having appropriate hardness can be obtained.

When not operated from the outside, the contact portion 331 of the present embodiment is maintained in a state of being in contact with the fixed shaft 22 by the elastic force of the plate spring 33 (see fig. 5 a).

When the locking member 32 is operated with a force greater than the elastic force of the plate spring 33, the protruding portion 332 passes over the fixed shaft 22, and the claw 321 moves from the unlocked state to the locked state (see fig. 5 b). At this time, the plate spring 3 slides on the fixed shaft 22 and moves. Accordingly, the operation lever 31 is lowered from the state shown in fig. 2 (see fig. 3). At this time, the upper surface of the operation handle 31 of the present embodiment is horizontal.

In this way, when the operation is performed with a force larger than the elastic force, the protruding portion 332 moves over the fixed shaft 22 and the abutting portion 331 moves away from the fixed shaft 22, and therefore, the claw portion 321 does not shift to the locked state unless the moving operation is performed, and thus, even if a force is applied to the lid portion 3 by an impact or the like, the lid portion 3 is not easily brought into the closed state.

In the above refrigerator 1, the lid 3 includes: a claw portion 321 as an engaging portion; a plate spring 33 as an elastic portion; and an abutting portion 331 (a portion of the plate spring 33, that is, the abutting portion 331) serving as a clamping portion, which is interlocked with the claw portion 321 and is disposed at a position where the claw portion 321 clamps the fixed shaft 22 when the claw portion 321 is engaged with the fixed shaft 22 serving as an engaged portion. Accordingly, when the operation is not performed from the outside, the distance between the claw portion 321 (specifically, the surface of the distal end of the claw portion 321 facing the contact portion 331 (the upper surface of the claw portion 321)) and the contact portion 331 is maintained in a state smaller than the cross-sectional dimension of the fixed shaft 22 (specifically, the diameter of the fixed shaft 22 having a circular cross-section), and thus the fixed shaft 22 does not pass (does not enter) the gap between the claw portion 321 and the contact portion 331, and therefore the claw portion 321 is maintained in a state in which the engagement with the fixed shaft 22 is released.

In the refrigerator 1, the claw 321 as the engaging portion and the contact portion 331 as the clamping portion are moved by the operation from the outside with a force larger than the elastic force of the plate spring 33, the claw 321 and the contact portion 331 are pressed against the fixed shaft 22, the claw 321 and the contact portion 331 are deformed so that the distance between the claw 321 and the contact portion 331 is larger than the sectional dimension of the fixed shaft 22, and the claw 321 is in the locked state.

In the refrigerator 1 of the present embodiment, the claw portion 321 is disposed below the fixed shaft 22 so as not to interfere with the fixed shaft 22 in the unlocked state (see fig. 5 a). Therefore, since the lid portion 3 is disposed in the depressed state, no gap is generated between the main body portion 2 and the lid portion 3, and therefore, compared to a refrigerator in which the claw portions 321 are disposed above the fixed shaft 22, cold air is less likely to escape from between the main body portion 2 and the lid portion 3 even in the unlocked state.

While the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

For example, in the refrigerator 1 of the above embodiment, the unlocked state is maintained by both the elastic force of the plate spring 33 as the elastic portion and the gap between the claw portion 321 as the engaging portion and the abutment portion 331 as the clamping portion, but the unlocked state may be maintained by either the elastic force of the elastic portion or the gap between the engaging portion and the clamping portion.

In addition, in the refrigerator 1 of the above embodiment, the fixed shaft 22 as the engaged portion provided in the main body portion 2 and the claw portion 321 as the engaging portion provided in the lid portion 3 are provided, but the main body portion 2 may have the engaging portion and the lid portion 3 may have the engaged portion.

In the above embodiment, the engaging portion is the claw portion 321, and the engaged portion is the fixed shaft 22. The elastic portion is a plate spring 33. However, the shape and the engagement form of these parts are not limited to the above embodiment, and may be implemented by various modifications.

For example, the contact portion 331 of the plate spring 33 in the above embodiment can contact the fixed shaft 22 of the body section 2, but may contact another portion of the body section 2. Specifically, it is conceivable to provide a flange portion extending outward of the opening 21 at a portion of the body 2 defining the opening 21 so that the contact portion 331 can contact the flange portion. In this case, the contact portion 331 can contact the body portion 2 at a position away from the claw portion 321.

Further, the plate spring 33 of the above embodiment extends downward on the front side of the fixed shaft 22 with respect to the fixed shaft 22 (right side in fig. 5a and 5b), and further extends from the front side of the fixed shaft 22 with respect to the fixed shaft 22 to the depth side of the fixed shaft 22 beyond the fixed shaft 22, but may extend downward on the depth side with respect to the fixed shaft 22 (left side in fig. 5a and 5b), and further extends from the depth side with respect to the fixed shaft 22 to the front side of the fixed shaft 22 beyond the fixed shaft 22.

The engaging portion (e.g., the claw portion 321) of the above embodiment is moved from the unlocked state to the locked state by being operated from the outside with a force larger than the elastic force of the elastic portion, but may be: even if such an operation is not performed, the lock state is moved from the unlock state to the lock state when a force capable of deforming the elastic portion is applied.

As the elastic portion of the above embodiment, instead of the plate spring 33, various types of springs such as a coil spring, rubber, a member having a restoring force such as a cushion mechanism using air pressure or hydraulic pressure, or the like may be used. Further, at least a part of the elastic portion may have an elastic force, or the entire elastic portion may not have an elastic force. For example, when a coil spring is used as the elastic portion, it is conceivable to use a structure in which the contact portion 331, the protruding portion 332, and the extended portion 333 are rigid members, and the protruding portion 332 and the extended portion 333 are connected by the coil spring.

In addition, the elastic portion may include the abutment portion 331 and not include the convex portion 332, and in this case, the abutment portion 331 is also maintained in a state of abutting against the lid portion 3 or a part of the body portion 2 by an elastic force of the elastic portion when not being operated from the outside.

Further, the through hole 326 may not be provided in the engaging piece main body, that is, the lock main body 323. In this case, the plate spring 33 may be configured to extend along the lock main body portion 323 without penetrating the lock main body portion 323.

The lid 3 of the above embodiment is "double-sided open", but the lid 3 may be configured to be "single-sided open" by providing a hinge that is inseparable from the body 2 on one of two parallel long sides in a planar view.

The operation portion of the above embodiment is the operation handle 31 that is movable in the vertical direction, but may be a slide member that is slidable in the horizontal direction. In this case, it is conceivable that the sliding member is slid to transmit a force generated by the sliding to the lock member 32, thereby moving the lock member 32 from the unlocked state to the locked state.

The lid 3 may be attached to the body of the existing refrigerator instead of the lid of the existing refrigerator. In the refrigerator having the replaced lid portion 3 attached to the main body portion, as in the refrigerator 1 of the above-described embodiment, when the operation is not performed from the outside, the engagement portion (the claw portion 321) is always maintained in a state where the engagement with the engaged portion (the fixed shaft 22) is released, and therefore, the lid portion 3 can be prevented from being held in the closed state without the user's intention. Therefore, the conventional refrigerator can be improved to a safer refrigerator by merely replacing the lid of the conventional refrigerator with the lid 3 as described above.
